To all whom it may concern:

Be it known that I, JOHN J. VnRwYs, a citizen of the United States residing at Sparta county of Kent, State of'Miehigan, have invented certain'new and "usefill 1m: provements in Revolving=Rack Showcases, ofwhich the following is a specification.

This invention relates to improvements in revolving rackshow cases. It relates more particularly to that style of; show case which appears in Letters Patent No. 1,023,186, issued April 16, 1912. j"

The object of this invention is to rovide improved Waysfor the carriage'and to provide improved interlocking means which prevents a rotation of the rack within the show case and until the rack is in forward position and locks the carriage in from; position until the rack is turned to position.

Objects pertaining to details and economies of construction and operationwill definitely appear from the detailed description to follow;

I accomplish the objects of the invention by the devices and means described in the following specification. The invention is clearly defined and pointed out inthe claims.

A structure embodying the features of the invention is clearly illustrated'in'the alccompanying' drawings forming a part "of this application, in which? Fig. I is a detail plan View of the car-' riage base bar of the'revolvingfrack and the ways for the carriage, the decking over the carriage being removed'andparts of the base bar being broken away to show de tails of construction, the forward position of the lock parts being indicated. by dotted lines. i

Fig. II is an enlarged detail transverse sectional elevation view, taken" on line 2 2 of Fig. I, the carriage appearing in full lines. l y

Fig. 111 is an enlarged detail plan View,

' portions of the latch being broken away,

showing the front position *of' the devices in full lines ready to lock the carriage on turn ng the rack, the preceding relation n dotted lines and 'the'lock disk and roller being also shown dotted. f

Fig. IV is an enlarged transverse detail sectional elevation View taken on irregular line H of Figs; '1 and III',par-ts' beis ;n ful lline'.

Isa-the drawings the --ses tioaa views are taken looking inthe direction of the little arrows atthe ends of the section lines and similar numerals of reference refer to simie lar parts throughout the several views.

Considering the numbered parts of the drawings by their numbers, 1 is the floor of the case. 2,9, are the transverseeross beams beneath the floor which support the carriage ways 4 for the transversely traveling garriage. IrThese are conneetedtogether by end bars; 3,3 (see Figs. 1 andII). The carrlage ways 4 supported by the said cross beams 2, 2 are provided with ball races 5,, 5 on their inclined faces to receive the bear-' ing balls 11. 6 is the front supporting cross bar connecting the side beams and rails together. 7 is the carriageyhaving brackets 8, 8 at each corner, in which are 'adj'ustably secured the longitudinal side rails 9 which are provided with ball races 10 disposed in position with obliquely under inclinedfaees to cooperate with the ball races 5 of the guide ways. I i

The faces of these guide rails and side railsyare slightly inclined so that the bear ing balls 11 rest upon a slight projecting ledge and also engage undera projecting or over hanging ledge on the carriage side rails. This insures their'smooth and even, action without shearing strain upon *the balls. The shearing action by this expedient is almost completely'avoided and the balls run much more. smoothly than between bars and rails with races in'their vertical faces, 12 is the upright column of the revolving rack supported on the ball bearing turntable 13. The base "bar carries the usual up right columns 15, 15 at each end which siip, portthe display rack 'at the upper end, these details not beingshown, as'my invention does not pertain "thereto.

12 and is notched at 22, 22 on opposite sides to receive suitable retaining or detent rollers 25. Levers 23, 23 are fulcrumed at 24, 24 toward the rear of said carriage, and project forwardly, each carrying one of the retaining or detent rollers 25, 25 to cooperate with the said notches 22, 22. The for ward ends of these levers are connected. by coil tension spring 26 which puts tension upon the same and causes them to engage the horizontal disk 21 yieldingly,'causing a slight braking action upon the revolving rack;

A laterally projecting locking latch 27 is pivoted at 27 towards the front end of one of the levers 23. This is notched at 27 and cooperates with the stop 28 securely bolted by the bolt or set screw 28 to the side rail 9 of the carriagesee Fig. IV. When the carriage is within the case it is inthe position shown by full lines in Fig. I and lever 23 with" detent roller 25 is locked against disk .21 preventing its rotation. The stop pin 29see Figs. III and IVlimits the movement of the said stop latch 27 which swings between the stop 28 and the forward end of the lever 23, positively retaining and locking the same in position as pointed out, until moved to the front of the case. Means are provided to release this look in front position. A lever 30, which has an offset portion 30,.is also supported on the pivot 27 and is pinned by pin 30, to said latch 27see Figs. I, III and IV, so that the latch and lever swing together. Lever 30 is pulled forward and held in forward position by the tension spring 31 which connects at the perforation 32 to the said lever and by screw 33 to the front corner of the carriage 7. Lever 30 is also a locking bolt.

The end of the lever 30 projects beyond the side edge of the carriage 7 and is disposed to cooperate with the stop 34 which is held by set screw" 35 to the guide rail 4. This stop block 34 has a stop portion 34 facing towards the front of the show case, and an engaging stop portion 36 facing toward the interior of the said show. case. These stops are in slightly offset relation, as appears in Figs. I and III. The end of lever 30 passes the inner stop on the outer travel of the carriage and strikes stop 36. The stop isso located that the movement of the carriage to the end of its ways swings lever 30 and with it latch 27 out of engage ment with stop 28. Thispermits lever 23 to swing in turning disk 21 and the end of lever 30 will be shot like a bolt in front of stop 34. s

Anti-friction roller 38 facilitates the movement of the said lever 30 into its stop position.

The relation of the interlock will be understood from an examination of Figs. I and III. When the carriage is in the in position indicated in Fig. I the latch 27 engages the stoppin 29 and holds the lever 23 firmly in position with the engaglng roller 25 in the notch 22, thus preventing the rotation of the carriage, and the rack is held in this locked position in relation to the carriage until the carriage is moved to the front of the case. lVhen the carriage is moved to the front of the case, the outer end of the lever 30 finally contacts with the stop portion 36 of the stop 34 and yields until the same is swung substantially to the right angle position indicated by the dotted lines of Fig.1, when the'forward spring catch 17 en gages the forward roller 18 and the stop 20 limits the further movement of the-carnage. This swings the latch 27 which is pinned to lever 30 out of enga 'ement withthe stop 28 and it is then possib e to revolve the rack of the show case, which lifts the roller '25, which is now free to yield, and swings the lever 23 to one side. This in turn forces the end of the latch lever 30 past the roller 38 so that it will engage with the stop 34. Then, because the latch lever 30 is thus engaged between the stops like a bolt, the can riage cannot be pushed in. The notched portion 27 then engages at one side of the stop 28 and because the end of the latch lever 30 is engaged by the stop 34 the carriage is locked in position andcannotbemoved back into the case until the revolving rack has been turned to the correct position cross way of the carriageto permit the same to be engaged by roller 25 and the latch lever withdrawn. When the rack is thus swung to the right position it is possible to move the carriage back into the case, automatically looking the rack against rotation at all times except when it is in the front position'where it is free to revolve and display the goods there on and at the same time lock the carriage in the front or display position.

I have described my improvements in the form preferred by me. The same can be variedas to details. However I desire to claim the invention in the specific form and also broadly, as pointed out in the appended claims. I Having thus described my inventionwhat I claim as new and desire to secure by Letters-Patent is:, V I H V 1.
